如何在scrapy中将单词(单词中的数字)转换为整数？

import scrapy

class MySpider(scrapy.Spider):
    name = 'my_spider'
    start_urls = ['http://example.com']

    def parse(self, response):
        word = response.xpath('//div[@class="word"]/text()').get()
        number = ''.join(filter(str.isdigit, word))
        if number.isdigit():
            integer = int(number)
            # 在这里可以对整数进行进一步处理或存储
            yield {
                'word': word,
                'integer': integer
            }
